The Sloth bear cub born at the Smithsonian's National Zoo Dec. 19, 2012, will debut in his yard Thursday. He is the first sloth bear cub born at the National Zoo in seven years. In a poll conducted on the Zoo's Facebook page, 830 fans elected to name the cub Hank, a moniker that combines the cubs' parents' names, Hana and Francois. The cub has spent the past six months bonding with Hana in a den near the Asia Trail exhibit. Animal care staff and the public have had the opportunity to watch Hana nurture the cub and watch him play and grow via the live Sloth Bear Cub Cam on the Zoo's website.
